In this embodiment, the humidifying device is a pure humidifying devicewhich pumps water from the water tank 202 to the water channel 241 byusing the water pump 205 and diffuses the water in the water channel 241into the air by means of natural evaporation, so as to achieve theeffect of humidification; in addition, a water level monitoring devicemay be provided in the water channel 241 to detect the level of water inthe water channel 241 in real time, when the water level is lower than aset water level, the water pump 205 is started to pump water, and whenthe water level reaches the set water level, the water pump 205 isstopped.

In some illustrative embodiments, the water channel 241 is provided witha water retaining sheet 2411 therein. The height of the water retainingsheet 2411 is smaller than the height of an outer wall 2412 of the waterchannel 241. The water retaining sheet 2411 functions to slow down theflow rate of the water when the water pump 205 pumps the water into thewater channel 241, so as to prevent the water from spilling out of thewater channel 241. The shape of the water retaining sheet 2411 may be asshown in FIG. 15, and the height of the water retaining sheet 2411 islower than that of the outer wall 2412 of the water channel 241, and isdesigned to be serrated to achieve the effect of slowing water flow.
